BACKGROUND: Hospitals that conduct more procedures on the carotid arteries may achieve better outcomes. In the context of ongoing reconfiguration of UK vascular services, this systematic review was conducted to evaluate the relationship between the volume of carotid procedures and outcomes, including mortality and stroke. METHODS: Searches of electronic databases identified studies that reported the effect of hospital or clinician volume on outcomes. Reference and citation searches were also performed...

BACKGROUND AND PURPOSE: The introduction of stent retrievers allows for a complete extraction and histological analysis of human thrombi. Ischemic stroke is a major health issue, and differentiation of underlying causes is highly relevant to prevent recurrent stroke. Therefore, histopathologic analysis of the embolic clots after removal may provide valuable information about underlying pathologies. This study analyzes histological clot composition and aims to identify specific patterns that might help to distinguish causes of ischemic stroke...

BACKGROUND AND PURPOSE: We investigated whether statin pretreatment can dose dependently reduce periprocedural complications in patients undergoing carotid artery stenting because of symptomatic carotid artery stenosis. METHODS: We enrolled a consecutive series of 397 symptomatic carotid artery stenosis (≥50% stenosis on conventional angiography) treated with carotid artery stenting at 2 tertiary university hospitals over a decade. Definition of periprocedural complications included any stroke, myocardial infarction, and death within 1 month after or during the procedure...

After a period of stagnation due to negative results of randomized trials for patients with symptomatic stenosis, the relevance of carotid artery stenting (CAS) is increasing again. CAS has become an important and evidence-based part of interventional stroke treatment. Our ability to manage acute recanalization of carotid occlusions and other niche indications properly led some skeptical neurologists to trust in carotid intervention for elective cases as well. The evolution of CAS from initial euphoria to more realistic views under consideration of trial results and guidelines is reviewed...

REVIEW
Jens Jordan
Device-based antihypertensive treatments have primarily been developed and clinically tested for patients with hypertension refractory to pharmacological treatment. Most but not all device-based treatments target the sympathetic nervous system and provided important new insight in the mechanisms of human hypertension. This review provides an overview on the scientific rational and clinical data on recent device-based antihypertensive treatment approaches. Device-based treatments targeting the sympathetic nervous system include catheter-based renal nerve ablation, electrical carotid sinus stimulation, modulation of baroreflex transduction through a dedicated carotid stent, carotid body denervation, and deep brain stimulation...

Atherosclerotic stenosis or occlusion often involves the subclavian artery. For lesions that are close to the orifice of the right subclavian artery, stenting of the right subclavian artery itself blocks the pathway from the innominate artery to the right carotid artery and causes problems in patients with multiple angiostenosis, especially involving the right carotid system. In this study, we report 2 cases using simultaneous kissing stenting (SKS) of the right subclavian artery and the right carotid artery to relieve right subclavian stenosis and maintain right carotid system patency...

BACKGROUND: One-month dual antiplatelet treatment, with aspirin and clopidogrel, following internal carotid artery stent placement is the current standard of care to prevent in-stent thrombosis. Cilostazol, an antiplatelet drug, has been demonstrated to have a safety profile comparable to aspirin and clopidogrel. OBJECTIVE: To evaluate the safety and clinical efficacy of cilostazol and aspirin therapy following internal carotid artery stent placement up to 1 month postprocedure...

BACKGROUND AND PURPOSE: Stent retriever thrombectomy and manual aspiration thrombectomy (MAT) have each been shown to lead to high rates of recanalization as single-modality endovascular stroke therapy. We sought to describe the safety and efficacy of a multimodal approach combining these two techniques termed 'stent retriever-mediated manual aspiration thrombectomy' (SMAT) and compared them to MAT alone. METHODS: Retrospective review of a prospectively acquired acute endovascular stroke database...

OBJECTIVE: High-degree stenosis of both innominate (IA) or left common carotid artery (CCA) and carotid bifurcation is uncommon but still represents a significant challenge to interventionists in many aspects including techniques, timing, and priority. There are several strategies for intervention that have been reported in the literature. A well-described, less-invasive strategy for extracranial tandem carotid lesions is concomitant carotid endarterectomy (CEA) with retrograde carotid angioplasty and stenting (CAS)...

Background Double lumen balloon catheters (DLBCs) are currently used in the treatment of intracranial aneurysms, especially when involving balloon or stent-assisted coiling. The existing DLBCs allow the delivery of self-expandable stents but do not offer the possibility to deploy flow-diverters. Despite the increasing use and success of flow-diverters, there have been numerous reports of procedural complications such as early in-stent thrombosis or delayed distal embolization. It seems that these complications can be avoided by correct stent positioning and adequate wall apposition, achieved either by manoeuvres with the microguidewire and/or microcatheter or by performing balloon angioplasty following an exchange guidewire manoeuvre...

Kosmas I Paraskevas, Frank J Veith
In the last 25 years, the very existence of carotid artery stenting (CAS) has been threatened on a number of occasions. The initial disappointing results that even lead to the discontinuation of an early randomized controlled trial have improved considerably with time. Novel devices, advanced stent and equipment technology, alternative types of access and several types of filters/emboli protecting devices have been reported to reduce stroke/death rates during/after CAS and improve CAS outcomes. The present review will provide a description of the various technology advances in the field that aim to reduce stroke and death rates associated with CAS...

REVIEW
Sung Hyuk Heo, Cheryl D Bushnell
As the population ages worldwide, the number of elderly patients with carotid stenosis is also increasing. There have been many large clinical trials comparing carotid endarterectomy (CAE) versus stenting, but the inclusion criteria (i.e., symptomatic or asymptomatic), stenting methods (i.e., protection device), and primary end point (i.e., the definition of myocardial infarction and follow-up period) were different between trials. Therefore, the interpretation of those results is difficult and requires attention...

BACKGROUND: Dissecting aneurysms of the basilar artery (BA) are rare lesions and the management of them has been controversial and challenging. The treatment becomes much more difficult when the patient has a disorder such as aortitis syndrome, which makes cerebral arteries occluded and tortuous. The authors describe a case of a ruptured BA dissecting aneurysm associated with aortitis syndrome, successfully treated with hybrid neurovascular surgery. CASE DESCRIPTION: A 64-year-old woman with a medical history of aortitis syndrome developed a severe headache and was diagnosed with a subarachnoid hemorrhage from a BA dissecting aneurysm...

BACKGROUND: In neuroendovascular therapy, the effect of arterial stiffness on postprocedural cerebral thromboembolism is unknown. In this observational study, we examined the relationship between cerebral thromboembolism after carotid artery stenting and arterial stiffness. METHODS: From April 2015 to February 2017, we enrolled consecutive patients undergoing scheduled carotid artery stenting in our institution. In all patients, preprocedural brachial-ankle pulse wave velocity was used to assess arterial stiffness, whereas the number of new cerebral ischemic lesions on diffusion-weighted magnetic resonance imaging was assessed after treatment...

BACKGROUND: One of the disadvantages of carotid artery stenting (CAS) is high incidence of distal embolism (DE) during or after the procedure. It has been reported that unstable plaque cases are at high risk of DE and plaque protrusion (PP) after stent placement which will become a cause of post procedural ischemic complications. OBJECTIVE: The purpose of this study was to compare the rate and size of PP between CASPER stent which is a new generation double-layer micromesh stent and conventional stents detected by optical frequency domain imaging (OFDI) and to evaluate the efficacy of CAS with CASPER stent for cases with unstable plaque...

A 56-year hypertensive, multiparous woman presented to the cardiology unit with Canadian Cardiovascular Society (CCS) class-III angina and worsening dyspnea for the past few weeks. Her clinical examination showed high blood pressure and mid-systolic crescendo-decrescendo murmur radiating to carotids. However, there was no radio-femoral delay or significant blood pressure difference between her arms. Her transthoracic echocardiography (TTE) revealed moderate aortic stenosis (AS) and mid cavity left ventricular outflow (LVO) obstruction...

BACKGROUND: We hypothesize that stenting of the internal carotid artery can immediately impede blood flow to the external carotid artery by either plaque shift or stent coverage of the ostium, and thereby cause ischemic symptoms like ipsilateral jaw claudication. METHODS: Thirty-three patients with high-grade asymptomatic stenosis of the internal carotid artery who underwent endovascular treatment were examined by ultrasound of the external carotid artery and performed an exercise test by chewing chewing gum synchronously to an electronic metronome for 3 min...

BACKGROUND: Information about carotid artery stenting (CAS) is largely derived from clinical trials, consensus statements, and outcomes comparisons between CAS and carotid endarterectomy. Given these limitations, the goal of this study was to identify risk factors for adverse outcomes after CAS among hospitals participating in the CAS-targeted American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). METHODS: Our study sample consisted of patients from the 2012 to 2015 CAS-targeted ACS NSQIP data set...
